Some Ukrainian researchers regard Constructive Art Nouveau as a transitional phase between Art Nouveau and Constructivist architecture. In Kharkiv, it emerged in the 1910s.

Architects seemed to sense the spirit of the coming era; Constructive Art Nouveau buildings had austere, rectangular forms, and their décor was also considerably more modest than in the 1900s. They often featured massive bay windows with large glazed areas – as if plucked from the Constructivist ‘buildings of the future’ of the 1920s.

At Poltavskyi Shliakh Street, 47/49 you can find a building in precisely this style. It was built in 1914–1915 as an apartment block for E. Feldman, housing the hospital of obstetrician Dr L. Margulis. The project was designed by architect Viktor Estrovich.

Unfortunately, the building’s original roof shape has not survived – from the side of the crossroads, it used to be topped by a dome. Many similar domes were lost from Kharkiv’s buildings following renovations during the Soviet era.

Whilst the façade facing Poltavskyi Shliakh features neoclassical details, the façade facing National Guard Square is distinguished precisely by its ‘structural’ bay window, similar to Constructivist buildings.

The building was damaged during the Russian attack on Kharkiv on 2 July 2025.
